Yeah, you bring up a good point, and I wish I could ask Dave that, but being as though I took my TJ from him yesterday, I don't imagine I'll have any time to pick his brain soon. What you're saying makes sense though, and it makes me question his reason for the bent arms even more.
Good point on KOH and JV. Yes, if a suspension can do well in that type of terrain, it's going to do well just about anywhere, no argument there. Which is again more reason that I'm glad I'm going with my gut here and putting the Savvy mid-arm on.
Lastly, it's very, very interesting you bring up the Rough Country long arm. Dave was talking to me yesterday about how he dislikes Metalcloak suspensions and Rough Country, as well as many others, since they don't work out the real details of the suspension geometry, they often just throw it together and don't pay attention to that. However, he said that believe it or not, one of the suspension systems that actually works really well is the Rough Country long arm. He said people who don't know anything will rip on it all day long online, but the way they designed it, it actually works quite well. He said he would never run it himself, but he mentioned it was one of the better designed systems he had seen in terms of "long arm kits". He had a bunch of technical reasons for this (such as the anti-squat being very good), but I can't remember them all.
Weird, huh? I would never think of buying anything from Rough Country.
